Chrome browser cannot access Facebook

My Google Chrome cannot access Facebook. It gives an error message – Your connection is not private. When I clicked on the advanced, it appears that I am trying to access a bogus site - but Facebook it is so there’s something wrong with the browser.
 
And to thicken the plot, here’s an added information. My home computer is a clone of my office computer, both having the same OS and practically the same hardware configuration. However, my office computer’s Chrome can access Facebook while my home computer cannot. So there, anyone?
